Introducing a new species, Silene Ghahremaninejadii (Caryophyllaceae), from Iran

Silene ghahremaninejadii (Caryophyllaceae) is described as a new species to science in this article based on critical differences in certain characters of both vegetative and reproductive organs, compared with its closely related taxa, i.e. S. marschallii and S. ruprechtii. The new species has compact caudex, glabrous leaves and pedicles, cylindrical calyx without indumentums on its inner surface, deeply bifid petals without coronal scales and glabrousfilaments. In addition, a hypothesis about the speciation process of the species is proposed.
